Anteater Racing Returns to Campus with Safety in Mind, Registers for 2021 Knowledge Events

After seven months, the doors are open for Anteater Racing at the UCI Vehicle Performance Engineering Lab. (“Vandal” shown behind the doors.)

We are back! Anteater Racing, upon receiving permission from the Henry Samueli School of Engineering at UC Irvine, resumed on-campus work on its SAE Collegiate Design Series competition vehicles with COVID-19 safety precautions. All three projects, Anteater Formula, Baja and Electric Racing, are currently manufacturing their vehicles at the Vehicle Performance Engineering Lab in anticipation for the 2021 Formula SAE and Baja SAE competitions. In addition, all three projects have successfully registered for their vehicle class’ Knowledge Events.

“Anteater Formula Racing is super excited to hear the good news that the team was granted access to the UCI School of Engineering Senior Design Project workspaces,” said Daniel Martinez, AFR Assistant Project Manager, Project Logistics. “Thank you to the Henry Samueli School of Engineering administrative staff and Professors Georgiou and McCarthy for helping us in this endeavor!”

Precautions include mandatory face coverings, frequent lab cleanings with disinfectants, reduced workspace personnel capacity, an online workspace booking procedure, and an online symptom check-in prior to arrival at facilities. Anteater Racing’s Project Members are only using spaces for essential manufacturing tasks, and they are continuing to hold meetings and perform all non-manufacturing tasks remotely. Members are also informed that they may opt out of on-campus tasks at any time.

Each project will spend Fall Quarter, October to mid-December, manufacturing their vehicles for the 2021 competitions. Anteater Electric Racing and Anteater Baja Racing both will construct new vehicles with inspiration and improvements from the 2019-20 season, titled “Ampeater II” and “Vandal II,” respectively. Anteater Formula Racing will finish “Jinx” as a two-year car with design upgrades developed during the COVID-19 manufacturing freeze.

With the pandemic, the SAE Collegiate Design Series announced changes to the event registration process for 2021. First, all teams in Formula SAE and Baja SAE register first for their Knowledge Events, which include the Design Event, Cost Event and Business Event/Sales Presentation, all of which will be held online. Once teams secure a spot, they will have the option to register again for the Validation Events, which include all of the trademark Dynamic events: Acceleration, Skidpad, Autocross, Endurance and Efficiency for Formula SAE and Acceleration, Hill Climb, Land Maneuverability, Suspension, and Endurance for Baja SAE. All three projects have successfully registered for their Knowledge Events, and all intend to register for Validation Events in November.

Anteater Racing Goes Virtual For This Year’s SAE CDS Competitions

In March, with 3 months to go before Formula SAE California and 1 month before Baja SAE Arizona, the organizers of the SAE Collegiate Design Series competitions called off the in-person “dynamic” events due to the dangers presented by COVID-19.

However, the presentation-based “static” events are set to take place beginning this week via video conferencing, and Anteater Racing’s engineers are preparing to give these modified competitions their best while also focusing on redesigning their vehicles.

“We have been practicing since the beginning of this quarter for the design presentation and since last quarter for the sales presentation,” says Anteater Baja Racing Chief Engineer Joseph Castro. 

The design presentation involves the teams’ lead engineers, who each present their areas of focus throughout the year to volunteer judges from the engineering industry. Normally, each team’s 2020 vehicle would join them in this event as part of the presentation.

“Anteater Electric Racing, like the other two teams, has split into two groups, a competition team and a design team,” adds AER Project Manager Janet Sepulveda. “We’re preparing for the Business and Sales Presentations by giving weekly presentations to our advisors and fellow team members. Their feedback helps us improve our presentations towards what the judges are looking for.”

“The Business and Sales presentations involve responses to business-related scenarios, which encourage engineers to think critically about the management aspects of the engineering industry,” Anteater Formula Racing Team Manager Noah Stein explains. “For FSAE‘s Presentation this year, we have to present an action plan that responds to a corporate-level decision to cut 90% of our Research and Development budget. And for the Cost event, we are proposing a cost reduction of our fuel system.”

“Baja’s Sales Presentation this year requires us to create a manufacturing company seeking investors for a production rate of 4,000 vehicles a year,” Castro adds.

Meanwhile, all 3 teams have continued their development in anticipation of the full competitions’ return in 2021. Electric and Baja are developing entirely new cars, while Formula is developing upgrades as part of a two-year cycle.

Baja’s major changes for the recently-announced Vandal Mk II come in response to new regulations allowing 4-wheel drive.

Castro: “Our biggest redesign comes from the new 4×4 feature, which has posed interesting new design changes in system integration and vehicle packaging. This has added new components and thus more weight. However, every subsystem (brakes, chassis, powertrain and suspension & steering) has been updated to accommodate the added powertrain system while also improving our reliability and maneuverability.”

Electric’s Ampeater Mk II will make the team much more competitive with performance upgrades:

Sepulveda: “We are focusing heavily on a full Aerodynamic package, the first ever for the Electric team, on integrating a data acquisition system that records speed, acceleration, temperature and GPS data, and modifying our steering to use full Ackermann steering.

Formula’s Jinx will also see significant improvements on its original design:

Stein: “While we’re unable to manufacture due to the shutdown, everyone is fully-focused on 10 new component designs that we can manufacture as soon as possible, such as a new intake plenum, exhaust rerouting, converting to a semi-monocoque chassis, paddle shifting, and electronic throttle control.”

Both the Virtual competitions and the push towards new designs mean that Spring Quarter, even in these circumstances, is still an opportunity for innovation for Anteater Racing.

 

AER: Developing a Comfortable Driver Fit with an Ergonomics Jig

Written by: Anteater Electric Racing Media

To produce results in the Formula SAE Competition, the ergonomics of the driver are just as important as the performance. Our 2020 FSAE Electric Racecar, named Ampeater, holds many components into a very small chassis, therefore making ergonomics critical to the operation of the vehicle. To resolve this problem, the development of an ergo jig was needed to research the ideal position of the driver inside the chassis so all mechanical components could be placed accordingly and taken to the Cal Club SCCA autocross event for feedback…

Component Introductions – Driver Input Module of the Lithium EV

This Blog is part 1 of a series of “Component Introductions” from Embedded System subteam of our FSAE Electric, with the goal of introducing and explaining the computer control modules used in the vehicle. This blog can also be read on the Electric Teams’ “The Track” webpage, found here.

The Texas Instruments MSP430 Launch Pad used for the DIM

 

What is the Driver Input Module?

The Driver Input Module (DIM) is a Texas Instruments MSP430G2ET (implemented with a G2553 integrated circuit) Micro-controller with the requirements of handling driver input of Lithium, UC Irvine’s 2019 FSAE Electric Racecar competing in Lincoln, Nebraska. The driver input includes two independent Accelerator Pedal Position Sensors (APPS), one Brake System Encoder (BSE), and one Steering Angle Position Sensor (SAPS). These inputs are processed by the DIM then forwarded to the Central Control Module (CCM) via CAN (Controller Area Network) with the use of a MCP2515/2551 CAN controller and transceiver.

Context of the DIM:

Context Diagram of the DIM

The figure to the right describes the context of the DIM. The driver input sensors (APPS, BSE, and SAPS) are analog potentiometers ranging from 0V-5V connected to the Analog-to-Digital Converter (ADC) of the DIM. The DIM utilizes this input data to check for faults in the system on a software level. Once the driver initiates the start sequence (applying brakes and pressing the start button) and no faults occur, these values are transmitted to the CCM of the racecar via the CANBus. Since the DIM micro-controller has no native CAN support, a MCP2515 CAN controller is connected via Serial Peripheral Interface (SPI) and a MCP2551 CAN transceiver is the interface between the aforementioned CAN controller and the physical CAN bus.

 

Description of the Faults:

“Faults” were previously mentioned and are critical to the design of the DIM for a tech-ready racecar. Faults can arise if the accelerator (depressed at >20%) and brake pedal are actuated at the same time, if there is a floating input voltage in either sensor, or if there is different APPS voltages between the two independent inputs. These faults are defined as a “plausibility” by the FSAE rulebook, and must be accounted for in our Failure Mode Effect Analysis (FMEA). If a plausibility occurs, the DIM will send throttle values of zero until the fault is cleared.

 

The DIM is essential for Lithium to be safe and tech-ready for final competition in Lincoln, Nebraska. This system is used to detect faults to prevent the racecar from transmitting incorrect pedal values for safe operation. Furthermore, the DIM provides hands-on experience with a microcontroller and interfacing it with CAN Bus to integrate it in a functional racecar for UC Irvine undergraduate Computer Engineers. DIM has been in development since the beginning of Fall 2018 quarter and is expected to be integration ready by February of 2019.
